Beschreibung des Produkts
For power-intensive contacting, HCF77512A400U500 (item number 1020968) provides a spring-loaded high-current path within the test setup. HCF77512A400U500 focuses on current capacity and low transition losses, as required in battery testing, formation and other e-mobility applications. For HCF77512A400U500, current capacity, low contact resistance and defined contact force are key to limiting electrical losses and unwanted heating. The design combines a pitch of 5 mm / 197 mil with tip style 12 (Spherical stepped) and a tip diameter of 4 mm. For HCF77512A400U500, spring force is 500 cN at a nominal travel of 4.4 mm. For HCF77512A400U500, the specified continuous current is 50 A.
